"We are using XSM for several years and so far we don't know faster sort sotfware on market, whatever the operating
system is. Setup of this sort tool into our batch jobs is a child's play and we have not yet detected any file size
limit. Congratulations to HHNS team for the quality of their tool as well as for their professionalism."

"Within 10 years, Base Plus turned from Small to Big Data. XSM is the only software we use from the beginning.
From few million records, we now sort over 1 billion lines files, still with outstanding performances."

- Base Plus, French Data Expert

Thank you for allowing me to evaluate your excellent product. In terms of performance it was
clearly the best product available on the market. I bench-tested it against a number of other
sort utilities and it performed at a minimum of 2.5x the speed of the other programs.

I am therefore in a position to recognise high quality, and your software is amazing.

"We use XSM on SUN Solaris mainly to sort large files having various formats. Thanks to
its performances and simplicity, XSM is the ideal tool to optimise our data sort and
deduplicate processes. Standart sort took 1h50m when XSM takes 10min44": Over 90%
performance improvement"

This says:
"We use XSM for its performances and its simplicity to use. Upgrade to v6 was simple and
gave 50% perf improvement on some critical processes. Support team is really good and reactive.
A global solution that matches our needs."

Thank you for the evaluation of your product.
We tried XSM, and it worked very well.
I liked the similarity to DFSORT. That is the best part. I would not think about changing XSM.
It is perfect as it is. It's simplicity is what gives it a plus.

Thanks again,

Dear Stephane,

We downloaded and conducted tests on multi-threading version and I'm happy to report that we
acheived fantastic, about 90% on average improvement in performance over our installed version
hxsm467_64.
We ran numerous tests on both versions using the same 400Mb binary file sorted by 3 keys under the
same conditions (very little activity on the machine).
On average the 4.67 version takes about 2m22 secs to sort while multi-threading version
hxsm642_aix5_ppc_64 does it in 1min 17secs.

I'm only using xsm now, just forgot about mine slooooow sort hehe.
.../...
The overall rating of xsm is very good, about 9 in a scale of 10.Very impressive tool. Certainly I will recomend to my friends.

Dear Mr. Henault,
XSM works perfectly and we couldn't find yet any bugs. We are absolutely satisfied with the
performance and functionality of XSM. Since my last benchmark tests comparing Smartsort with XSM,
I have no new benchmark results.

This says:
NORMAD1 SA, French leader in Address normalisation for postal mailing, recommends XSM to its clients because of XSM
performances on large files.
NORMAD1 also asked HH&S to port XSM to OS/400, which we did immediately.

This guy from Oracle answers a question on a database forum about external data sorting
and merging (read our article about external sorting).
He gives XSM as an example of existing software.
